Crop yield is directly related to the speed of plant growth, the final size and shape of the harvested organ, and the reproductive success leading to seed set and fruit formation. The formation of leaves, shoots, roots and fruits is the result of concerted cellular activities: cell division and cell growth. The Geitmann Lab studies how these fundamental processes function at subcellular level with the aim to understand how the genetic composition of an organism translates into its characteristic shape, form and functionality.
